  • Publication number: 20140212766
    Abstract: The invention herein described is the use of a block copolymer/homopolymer blend for creating nanoporous materials for transport applications. Specifically, this is demonstrated by using the block copolymer poly(styrene-block-ethylene-block-styrene) (SES) and blending it with homopolymer polystyrene (PS). After blending the polymers, a film is cast, and the film is submerged in tetrahydrofuran, which removes the PS. This creates a nanoporous polymer film, whereby the holes are lined with PS. Control of morphology of the system is achieved by manipulating the amount of PS added and the relative size of the PS added. The porous nature of these films was demonstrated by measuring the ionic conductivity in a traditional battery electrolyte, 1M LiPF6 in EC/DEC (1:1 v/v) using AC impedance spectroscopy and comparing these results to commercially available battery separators.

  • Patent number: 8728364
    Abstract: A foam form sheet material having a first large surface comprising substantially only closed cells and an opposite large surface and an interior comprising substantially only open cells. This material comprises a cross linked olefin thermoplastic polymer or copolymer. The foam is made by mixing the polymer with a blowing agent and a cross linking agent. The mixture is maintained in a two roll mill means for a time sufficient to initiate cross linking and to initiate foaming to form closed cells. The sheet material is then disposed in a second two roll mill means having a nip that is larger than the thickness of the foamed sheet material and maintained under elevated temperature and pressure sufficient to initiate further cross linking and foaming. The fully cross linked cell foam is then compressed to rupture the closed cells that are disposed in the interior to form open cells.

    Abstract: As detailed herein, a biocompatible apparatus comprises a porous material comprising ceramic nanotubes bound together with a filler material. The proportion of the filler material may be selected to provide porosity for the porous material that is biocompatible, and the porous material may be shaped to provide a compliant biomedical device. In one embodiment, the compliant biomedical device is a stent such as intravascular stent. A method for fabricating a biocompatible device is also described herein. The method may include growing ceramic nanotubes on a substrate, infiltrating the ceramic nanotubes with a filler material to provide a porous material having a porosity that is biocompatible, and removing the porous material from the substrate to provide a biocompatible ceramic device. The method may also include coating the biocompatible ceramic device with a drug-eluting material.
